20100061404 | METHOD FOR STARTING A COMMUNICATION SYSTEM, A COMMUNICATION SYSTEM HAVING A COMMUNICATION MEDIUM AND A PLURALITY OF SUBSCRIBERS CONNECTED THERETO, AND SUBSCRIBERS OF SUCH A COMMUNICATION SYSTEM - A communication system having a communication medium and at least two subscribers connected thereto is described; the communication system being designed for transmitting data among the subscribers via the communication medium in communication frames of communication cycles via a time-triggered protocol. To accelerate the start of the communication system before the actual data transmission, the communication system has a device for generating at least two different synchronization frames per communication cycle and per channel, in at least one of the subscribers, e.g., in the node AB. For example, the device is designed as two separate communication controllers per transmission channel. As an alternative, the device may also be designed as a simple logic circuit, a so-called application-specific standard product. For generating the at least two different synchronization frames per communication cycle, the subscriber is designed as an active star coupler of the communication system. Data transmission in the communication system is preferably performed using the FlexRay protocol. | 03-11-2010 |
20100161834 | USER INTERFACE BETWEEN A MICROCONTROLLER AND A FLEXRAY COMMUNICATIONS MODULE; FLEXRAY USER; AND METHOD FOR TRANSMITTING MESSAGES VIA SUCH AN INTERFACE - A user interface between a FlexRay communications module which is connected to a FlexRay communications link over which messages are transmitted and which includes a message memory for buffer storing messages from the FlexRay communications link or for the FlexRay communications link, and a microcontroller which is assigned to the FlexRay communications module and which includes a microprocessor and a direct memory access (DMA) controller for exchanging data with the message memory. In order for the DMA controller of the microcontroller to be connected more effectively to the FlexRay communications module, the user interface has a state machine, which, once configured by the microprocessor of the microcontroller, independently coordinates and controls a data transmission between the message memory of the FlexRay communications module and the DMA controller. | 06-24-2010 |
